Technical field
The present invention relates to a kind of lighting device, especially relate to a kind of optics ring lighting device.
Background technology
The details in a play not acted out on stage, but told through dialogues microtechnic has obtained very using widely, and its feature is different with bright field illumination, does not observe directly the light of illumination, but observes the light of checking matter volume scattering.Therefore, the visual field becomes dark background, and seized object then presents bright picture.Because scattered signal is a lot of a little less than than excitation line, in order to guarantee dark visual field background, therefore needs the annular beam of high angle incident, also can not get into the collection camera lens with the excitation line that guarantees reflection.
Because most central ray has been blocked; In order to guarantee that there is enough brightness in the visual field; Apparatus manufacture designs and has improved the power of lighting source; But this method does not have the reasonable use energy of light source to cause certain waste, and the heat that distributes has in a large number simultaneously promoted the temperature of surrounding environment, has reduced the stability of instrument.
For the experiment of some fluorescence or Raman like surface plasma body resonant vibration hereinafter to be referred as SPR, total internal reflection hereinafter to be referred as ATR; It all needs the exciting light of high angle incident to excite the plasma resonance SPR or the formation that produce sample surfaces to reach the required angle of total internal reflection, and this equally also needs annular beam (1.J.J.Baumberg, T.A.Kelf; Et al.; Nano Lett., 5 (11), 2262 (2005); 2.K.J.Mckee, E.A.Smith, Rev.Sci.Instrum., 81043106 (2010)).Laser for Gaussian distribution; Core light has occupied most energy, and after blocking, the light on next door is just very weak; And the power of miniature laser itself is conditional at present, therefore is badly in need of a kind of method and obtains high-power annular beam to satisfy the demand of experiment.
Simultaneously; Along with the application of radial polarisation light in the super-resolution optical microscope, theory shows that annular beam radial polarisation light can further obtain littler focal beam spot (3.R.Dorn, S.Qquabis through behind the high-NA objective; G.Leuchs; Phys.Rev.Lett., 91 (23), 233901 (2003)).This also needs a kind of ability to produce high-power laser annular illumination system urgently.
Summary of the invention
